Architectural masterpiece with private St. Croix River frontage! Nestled on over 2 acres, this extraordinary Hudson home is a one-of-a-kind Michael McGuire original, designed in the spirit of Frank Lloyd Wright, blending seamlessly into its bluffside setting with timeless natural materials and organic design. Built into the landscape for ultimate privacy and tranquility, the home sits below the road, shielding it from traffic noise and immersing it in nature. The striking A-frame upper level lives like a summer retreat, open and airy like a canvas tent, while the lower level, surrounded by windows on all sides, offers cozy, year-round comfort with the feel of a temperate cave. This 2-bedroom, 2-bath sanctuary offers sweeping views from every angle and effortless indoor-outdoor flow. Step onto the wraparound deck or relax on the limestone patio and terraces that descend toward your very own stretch of shoreline, approximately 270 feet of private access. A floating pier deck and a multi-level limestone amphitheater create the perfect setting for gatherings, sunrises, and riverfront serenity. Located just a short walk to the scenic new Stillwater Bridge loop for biking and walking, this property is not only a home, but a lifestyle. Original architectural blueprints are included, an inspiring bonus for those who appreciate intentional design. A rare opportunity to own a modern classic on the river. Don’t miss it!
